Introduction
All data points shown in this document are transmitted by default via the OPC UA PubSub (MQTT) protocol.
As an option, the transmission of Harmonics and Energy values can be disabled during the device configura-
tion in order to reduce the data volume if necessary.
In addition to these data points a file with device asset information (serial number, order number etc.) is trans-
mitted during the communication startup and every 2 hours after communication startup when the communi-
cation is established.
For options to adapt and select the published data points, refer to the SICAM Q200, 7KG97xx Device Manual,
V02.50.
General Remarks for the Mapping of Measured Values and Harmonics
The described default mapping presupposes that:
•
All harmonics are enabled on the
OPC UA PubSub (MQTT)
configuration page and no imported
mapping file is used.
By default, all measured values and harmonics are transmitted as aggregated values.
For each aggregated measured value 3 data points (average, minimum, maximum) and for each aggregated
harmonics 2 data points (average, maximum) are published.
The average value of the frequency has an independent, fixed aggregation interval of 10 s and the prefix is
PQA4.
